If you think the Supreme Court is going to defend the constitution your sorely mistaken as well. In its 200 year history, with thousands of unconstitutional federal laws on the books. The Supreme Court declared less then 180 unconstitutional and most of them were only partially stricken. Even the founders realized the Supreme Court failed.
Trump is only looking out for his own interest. After all he extended many of the provisions of the patriot act. Even criticizing the most constitutional congressmen in congress because they where against it. The hypocrisy is real
Your "defend the Constitution" is a pretty broad statement. Do I expect them to defend the Constitution based on my understanding of the Constitution in every circumstance? I think to do so would be a little naive. While we on the forum talk about 2nd Amendment rights my guess is there are 101 different options on just what those rights entail. Even among the so-called conservative members of the court you get a split of opinions.
As there been judicial creep over the last two hundred years? Absolutely, just as there has been moral/social creep in our society as a whole. Every generation has to keep fighting to prevent, slow it down and if possible reverse it.
So I understand your compliant but I think the phrase "defend the Constitution" is too broad a statement and ultimately non-productive. These issues have to be attacked issue by issue (targeted) versus a shotgun approach that gets us nowhere.
